HAY-RAKE.

Speccaton of Letters Patent. y

Patented Aug'. 14,' 1906.

I Application filed September 5, 1905. Serial No. 276,978.

T0 @ZZ whoml it may concern,.-

Be it known that I, HENRY F. RODEMEYER, a citizen of the United States,residing at Sterling, in the county of Whiteside and State of Illinois,have invented a new and useful Improvement in Hay-Rakes, of which thefollowing is a specification. j

My invention relates more especially to an improvement in the class ofside-.delivery hay-rakes wherein the-frame which carries the rakingmechanism is supported at its outer end on a caster-wheel; and itrelates particularly to means for facilitating adjustment of the frameon said support with relation to the ground-surface to raise and lowerthe rake-teeth.

I have especially devised my improvement for use with the hay-rakeforming the subject of United States reissued Letters Patent No. 12,194,dated January 19, 1904, and therefore illustrate it in that particularconnection in the accompanying drawings, in which- Figure 1 is a planview of a side-delivery hay-rake equipped with my improved frame raisingand lowering means; Fig. 2, an enlarged view showing the adjusting meansforming my improvement in elevation; and Fig. 3, a view like thatpresented by Fig. 2, but showing the adjusting means in section, thesection being taken at the line 3 on Fig. 1 and viewed in the directionof the arrow.

A denotes the rake-frame, supported at one end on the frame B, carriedby the axle O, and with which the draft-rigging D is connected, therake-frame being supported on a hanger-beam E, mounted at one end on theframe B and adjustably supported at-its opposite end on the groundthrough the medium of my improved means for the purpose of which thefollowing is a description. n

F is the supporting-wheel, j ournaled in the lower end of a yoke a, theupper end of which is rigidly fastened to the lower end of a stem G, thewheel with its stem forming a species of casten On the stem is formed orotherwise provided between its ends a screwthread b, with whichcoperates an internallythreaded 'sleeve or nut c, surrounding the stemand secured against rotation when set by a set-screw c. A channeled seatd for the end of the hanger-beam E is bolted to the latter andterminates in a vertical sleeve e,

through which the stem G passes loosely and which is surmounted by astop-collarf, surrounding the stem and vertically adjustable thereon,being provided with a set-screw f for securing it in adjusted position.The stem passes toward its lower end loosely through a sleeve g, seatedin a socket g', having arms g2 projecting from it and by which it issecurely fastened to the frame A. Between the sleeves e and c isconfined a coiled stiff cushioning-spring h, surrounding the stem G andthrough the medium of which the wheel-supported end of the rake-frame isspring-carried.

To raise the frame A with relation to the ground, the collar f is raisedto its desired point on the stem G and there` fastened by theset-screwj, when the nut c, upon loosening the set-screw, is turned toraise the spring '7L and with it the sleeve e, and with the latter thebeam E and frame A, carried by it until stopped by the collar j,whereupon the nut is fastened by its set-screw c. rake-frame, the nut c,after loosening it, is turned in the contrary direction and the gravityof the parts carried by it causes the sleeves e and g to follow it alongthe stem G. When the frame has thus been lowered to the desiredposition, the nut c is fastened by its set-screw and the collar f isloosened on the stem against the upper end of the cushioning-spring andfastener to confine the latter by the set-screwf.

The construction thus described of my improved adjusting device rendersit simple and quickly operative under all conditions with great facilityfor raising the frame of a side-delivery hay-rake and that of any otheragricultural or analogous machine having a frame or part end-supportedon a Wheel through the medium of a stem extending from the latter andadapted to carry adjustably upon it the members of my improved deviceconnected with the frame or other part to be supported. Hence I desireto be understood as intending my improvement for use lin all connectionsof the kind thus sugested as well as in the particular connection orwhich'Ihave especially designed it, as

aforesaid.

What I claim as new, and desire to secure by Letters Patent, is*

1. In a side-delivery hay-rake, the combiloo nation with the hanger-beamand rake-frame supported thereon, of an upper sleeve extending from saidbeam, a lower sleeve Connected with said frame, a wheel having a sternpassing through *said sleeves and provided between them with ascrew-thread, a nut engaging said thread, a spring confined between saidnut and upper sleeve, and a stop adjustable on the stern above saidupper sleeve, for the purpose set forth. l

2. In a side-delivery hay-rake, the combi* nation with the hanger-beamand rake-frame supported thereon, of a seat secured to said beam, andterminating in a sleeve, a socket connected with said frame andcontaining a 15 sleeve, a wheel having a stern passin through saidsleeves and provided between t ern with i y screw, for the purpose setforth.
